BRlQUET-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 718,043, dated January 6, 1903.

Application filed February 19, 1902. Serial No. 94,755. (No model.)

To all whom. it may concern;

Be it known that I, ELLSWORTH B. A. ZWOYER, a citizen of the United States, and a resident of Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Briquet-Making Machines, of which the following is a specification.

This invention relates to means for molding briquets or blocks from comminuted material. Its object is the production of machines in whichind entations, pockets, or cavities on the circumferential surfaces of cylinders or rolls will form briquets and the like when the said cylinders or rolls are rolled together, and the specific improvement forming the subject-matter of this invention relates to the formation of the pockets on the said cylinders or rolls.

In the rolls contained in my invention indentations, pockets, or cavities are formedin disks comprising the said rolls and arranged so that a portion, generally one half of the said indentation, 850., is on one disk and the accompanying portion or other half of the said indentation is on the next adjacent disk, by virtue of which construction the said pockets or cavities can be easily machined to obtain perfectly smooth surfaces of any desirable form.

In the accompanying drawings my invention is shown applied to a coal-briquet-molding machine; but itis of universal application.

Figure 1 represents an elevation of a briquetmolding machine with my improvement. Fig. 2 is a top View of Fig. 1. Fig. 3 shows an end view of Fig. 1. Fig. 4 represents a partial end view of one of my rolls with a partial section through its axis on an enlarged scale. Fig. 5 is a partial side view of my rolls and section of Fig. 4 on the line at a; on an enlarged scale. Fig. 6 represents a perspective view of a fragmentary portion of one of my disks on an enlarged scale.

Referring to thedrawings, the rolls A turn with the shafts B B in the journal-boxes O and adjustable bearings D, carried on the frame E, the latter being supported on the legs F. The caps G serve for both the top halves of the journal-boxes C and for the covers of the adjustable bearings D.

The shaft B carries the spur-gear H, which meshes'with the gear H on the shaft B. On the shaft B there is also secured the spurwheel I, which meshes with the pinion J, carried on the shaft K, turning in the bearings K. A pulley L on the shaft K receives power from any convenient source, which is transmitted to the rolls through the train of gearing. A key M is fitted between the caps G and the frame E for stability.

The bearings D can be adjusted along the longitudinal direction of the machine by means of the screws 0 and P, which turn through the frame E.

The rolls A, constituting the distinctive feature of this invention, comprise disks A, the circumferential surfaces of each of which contain a narrow central ridge at around the same, with narrow cross-ridges a at right angles thereto, all at the outermost portion of the circumferential surfaces of the said disks. The surfaces between the said ridges are concaved to form indentations, pockets, or cavities ct, which can be of any shape, and it is evident that tools can easily operate between the said ridges before the disks are clamped together to secure smooth surfaces for the pockets, which are essential in this class of machines. Y

The disks A are bolted together with bolts a so that the ridges a in all of the disks come in line, thereby bringing the cavities a. of one disk opposite or in line with the corresponding'cavities of a disk next adjoining, and consequently form pockets with smooth surfaces.

Both rolls have similar pockets and are secured on their respective shafts, so that when they roll the cavities will come exactly opposite at their point of tangency to form molds for the material passing between them.

It is evident that more than two rolls could be used. In fact, any combination by means of which the briquets could be formed might be employed.

To operate the machine, any source of power turns the pulley L, which motion is transmitted to the rolls A, the material being fed to and between the rolls at the top of the same,and the briquets drop therefrom at their lower sides.

Having described my invention, I claim- 1. In a briquet-molding machine, the combination of rolls tangent to each other, disks secured together forming the rolls, a circumferential ridge on each disk, ridges at right angles to the circumferential ridges and in the circumferential surfaces of the disks, cavities on the sides of the circumferential ridges and between the ridges at right angles thereto, and means for driving the rolls.

2. In a briquet-molding machine, the combination of rolls, disks secured together forming the rolls, a circumferential ridge on each disk, ridges making angles with the circumferential ridge andin the circumferential surface of the disk, cavities on the side of the circumferential ridges and between the ridges at right angles thereto, shafts supporting the rolls, adjustable bearings for one of a pair of rolls, and means for driving the rolls.

3. The combination in a briquet-molding machine of rolls, disks secured together comprising the rolls, cavities in the circumferential surfaces of the disks disposed so that the cavities of one disk will come opposite cavities on a disk secured adjacent thereto, a pinion-shaft, shafts supporting the rolls, adjustable bearings for one of these latter shafts, spur-gears meshing with each other on the shafts supporting the rolls, a gearwheel on the opposite end of one of the shafts supporting the spur-gears, a pinion driving said gear-wheel, a driving-pulley on the pin ion-shaft, and a frame to support the elements.

Signed at New York, in the county of New York and State of New York, this 8th day of February, A. D. 1902.
